SHAKER-PLATE FOR ORE AND COAL LltZASd.

To all whom it may eoncern Be it known that I, Mosns JAMES, citizen ofthe United States, residing at Lansford, in the county of Carbon andState of Pennsylvania, have invented certain new and useful Improvementsin Shaker-Plates for Ore and Coal Washers, of which the fol- 1 lowing isa specification. I

T his invention relates toimprovements in the shaker plates of ore andcoal Washers.

It is one aim of the invention to provide a shaker plate so formed thatin operation it will act to effectually spread the material '7 be thrownup from the plate to a greater or ess extent, as distinguished frombeing merely shifted back and forth upon the surface of the plate,'aswould be the case if a plane shaker plate were employed. This agitationof the material of course serves to bring dlfferentportions of the massinto contact with the surface of the plate, sue-- cessively, therebyinsuring ing of all port ons.

thorough wash-- to strengthen the plate and prevent its sagging, whichis likely to occur in the use of a plane plate.

Another aim of the invention is to so'constructand arrange the rifllesthat the material will be retarded inits movement over the surface ofthe plate, thereby further ing suring thorough washing of the material.

Still further the invention has as its aim to provide .a riftleplate ofsuch formation that it may be employedfin treating ore or coal Whetherin wet or dry conditlon, In the accompanyin'gdrawmgs; Figure 'l i is aplan View of the shaker plate embodying the present invention Fig. 21s asec j e be e their ends opposlte their merging. ends, the

Corresponding and like parts are referred to in thefollowing descriptionand indicated in alljthe views of the accompanying drawingsby the samereference characters.

The invention also contemplates so form 111g and-arranging the rlifles1n the plate as The rifiieplates are of course arrangedin a serieswithin the shaker frame, and inasmuch as all of the plates areof thesame construction, a description of'one Will suffice forall, 1 w

The riflle plate embodying the invention is preferably stampedfrom-sheet metal and is. indicated in general by the numeral l. Thefront to rear median line of the plate Specification of Letters Patent.Patented Jung 8, 1915,. r Application filed May 28,1914. Seria1 No.841,5 86.

is indicated by the dot and dash line 1n F1g.1, and theriffles formed inthe plate j are arranged, in a manner to'be presently described, in acertaln definite relation'to th1s line, the r ffles belng located Withina 'certaindefinite area, the boundary lines of, which are spacedinwardly from the edges of I the plateso that the edge portions of theplate are leftplane, whereby to serve'as attaching andc0nnec'tingflangesr One'of these edge portionsylocated at onelongitu-aopposite edgeportion is indicated by the numera -let and ispreferably slightly-wider 1 than the edge portion?2 and formedv ith:

two series of 0 enin s 5. Each lateraledge portion of the plate isindicated atG and.

is formed with'openings 7.

, The riffles are formed by stamping the 1 plate with alternatingridges" and valleys at I I each side of its front to rear median line;The rlflles are arranged in two series, one 10' cated" atjeach f side ofthe front to rearmedian, line of'the plate and the arrangement in'thetwo'se'ries is the same.- Certain of the riflies of each series areindicated the numeral 8 and the other riffles of each series areindicated by the numeralti. Corresponding ones of the first-mentionedElfl'lQS of the two series'tm'erge or unite at their inner ends alongthe median'line, and the said rifflesextend in opposite directions fromthis line diagonally, from-the plate and in thegeneraldirection of theadjacent corner. 'of-the plate, the rlffles of each series being,however, par'allelfto each :other and being furthermorepreferably atright angles to corresponding rilflesf of the iotherseries. At

rilfles merge into the ear-face of the plate,

It willlalso be apparent-by reference to Fig.

. 1 that the riffles' of theftwo series diverge in. the directionqofftheedgeportion 4 of the plate. lThe riifles 9 of eachseries extendparalljel to the riflies 8. of the same series but do I wardlytherefrom.

not merge at their adjacent en .s, they being arranged diagonally withinthe corner of the plate neXt adjacent which the longer ones of theritlles 8 are located, and being gradually decreased in length as they,in the series, approach the said corner. Inasmuch as the rifles 9 of theother series do not merge or join each other, they inerge at both endswith the surface of the plate. l he shaker plate is provided throughoutits riflle area with nunicer of perforations 10 through which the watermay drain during the washing operation.

The manner of arranging the plates within a shalrer frame is clearlyillustrated in Fig. 3 of the drawings, the numeral 11 indicating theframe in general and the said frame being of the ordinary form andprovided at the lower edges of its sides with L angle iron bars 12 whichhave a vertical secured to the inner face of the said side andhorizontal. flange projecting in- The lateral edge por tions 6 of theplates are bolted or otherwise secured to the horizontal flanges of theangle iron bars, and bolts are passed through the openings 3 and 5 i theoverlapped edge portions 2 and 4; the series plates and through crossbars 13 secured at their ends, to the horizontal flanges of the angleiron bars and extending transversely beneath the said side portions 3and 4-. By reference to the said 3 it will be observed that the plate,located t is intake end of the frame, which end of the frame isindicated by the numeral 15, is so arranged that its riffles willconverge or be inclined toward that end of the frame. he next plate inthe series is arranged in cr ed position, however, and this relativearrangement of each two of the plates is continued throughout theseries. It will now be apparent that when the mate rial is introducedinto the shalrer frame, it

will be separated and agitated, and due to the fact that the riiiles orthe second plate in the series of plates diverge toward the outlet endof the frame, the niaterial will be spread and separated at each side ofthe front to rear niedian line ofthe frame. As he material passes ontothe second plate in the series, the mass is concentrated or gath redtoward the said longitudinal inedian line of the frame, and as it passesonto the third plate of the series, it will again be spread in the sanemanner as when passing over the first plate of the seies. lit will beunderstood, of course,that the riilles will serve to up from the surraceof the plates andfthat the material is shifted'not only back and forthbut also from side to side, so that it is thoroughly agitated and moreeffectually washed would be possible by the use structed throw thematerial 01 a plane perforated plate. will also be understood that thevalleys of riflies will tend to collect and retain the water, thereoypreventing the same passing too quickly or freely through the opening10.

It will be observed that the plates embodying the present-invention haveplane or marginal portions, and it will further be observed by referenceto Fig. 3 that when a number of the plates are assembled in series withtheir said marginal portions overlapped, distributing channels will bepro iced between the said plates.

Having thus described the invention, what is claimed as new is:

l. in a device of the class described frame, a alurality of shakerplates arra within the frame, each plate being provio at each site ofits median line with a series of riflles, tlie rifties of the two seriesupon each plate meeting at the median line of the plate and the rifiiesof one series extending an angle with respect to the rifles of the oth rseries, the plates being arrange within the frame with the riflies ofthe two series alternately diverging in the direction of the oppositeends of the frame.

2. A shalrer plate of the class described haying marginal portions andformed within th bounds of tlie said portions with a raised rililedressing, certain of the ginal portions being constructed to overlapsimilar portions of the other ones of the plates when a number of theplates assembled ged ed in series, and being furtl er conto permit ofthe said portions being secured together in their overlapped relationand adapted with a mating plate to form distributing channels betweensaid plates.

3. A. shaker plate of the class described ha ing flat marginal portionsand formed within the bounce of the said marginal portions withdiagonally extending raised corrugations arranged in series at oppositesides of the longitudinal median line of the plate, the corrugations ofthe two series converging toward and meeting at the said line and eachterminating at one end at the marginal portion at one side of the plate,the front and rear marginal portions of the plate being connected tooverlap and be secured to similar portions of other similarlyconstructed plates when a of the plates are arranged in a series andadapted with a mating plate to form distributing channels between said,plates.
